T all whom it may mm f 1 Beit known that 1,]ARN0 A. Ewnnma citizen of the United States, residing. at

. Oakfield, in the county of FondduLac and State of Wisconsin, have invented certain new and .useful Improvements in Tire- Stapling Machines; and do declare the fol lowing to. be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which itappertains to make and use the same. My inventionhas for its object to provide an extremely simple and comparatively inexpensive, yet a highly. efiicient and reliable device whereby two old tire casings maybe stapled together in order that additional mileage may be obtained therefrom. y With the foregoing object in view, the

invention resides in the novel features of tilt construction and unique association ofparts hereinafter fully described and claimed, reference being made to the. accompanying drawings which form a part ofthisapplication.

Figure 1 is a side elevation of the machine showing the manner in which it is used upon the casings.

Fig. 2 is a front edge view.

Figs. 3 and 4 are horizontal sections-0n the planes of the lines 3-3 and H respectively of Fig. 1.

Fig. 5 is a detail vertical transverse section on the planes indicated by the line 55 of Fig. 1 showing the staple housed within its guide preparatory to driving.

Fig. 6 is a view similar to Fig. 5 but illustrating the staple projected through the two tire casings and clenched upon the anvil,

"In the drawings above briefly described, the numeral 1 designates a preferablv cast metal standard having suitable seats 2 adapted to be secured to a work bench or the like, the upper end of said standard being bifurcated at 3 and carrying a lever 4 provided with a earn 5 for depressing a plunger 6 whose lower end is shaped at 7 to form an anvil for clenching the staples. The plunger 6 is slidably mounted in a bearing 8 carried by an arm 9 projecting forwardly from the standard 1, and a spring 10 is employed for normally raising said plunger to the position of Fig. 1.

Another arm 11 extends forwardly from the standard 1 below the arm 9 and is proaided on its outer end with a vertical rib Specification of Letters Patent.

1e si nna; which a. steamy elongated staple gulde 13 is slidably mounted as shown clearly in Figs. 1, 5 and 6. The rib 12 serves as a stapledrlven and since it 1s necessary that it be of hardened metal, it is by prefer en ce "formed separatelyfrom the arm 11 and suitably secured thereto, said rib being shown ,in presentembodinient of the device as carried by a plate 14- receivable in a notch 15 in the arm 11 and secured in place bybolts 16 (see more particularly Fig. 4:).

. A horizontal work supporting plate 17 is suitably secured. upon and extends rearwardlyfrom the upper .endof the staple guide 13, thefront end of said plate inclining downwardly and forwardly at 18. and

then downwardly and rearwardly at 19 to the loweiyend of-.theguide 13, being provided with an upstanding flange 20 secured to the frontside of said guide. Suitable springs 21 are secured in one end to the standard 1 and at their. other ends passed through openings in the-flange 20, whereby to normallyproject the guide 13 sufiiciently above the rib 12 to allow for the insertion of astaple 22gi'nto said guide as shown clearly in Fig. 5. Since the plate 17 is secured to the guide 13, itmoves bodily there- .with, the upward movement being limited by the springs 21 coming in contact with the lower side of the arm 11. The forma tion 18-19 of the plate 17 forms a wedge shaped spreader for reception in the innermost tire casing shown clearly in Fig. 1, whereby to force the sides of such casing outwardly into tight contact with the sides of the outer casing. The construction in question also allows the casing to be easily moved into place upon the machine.

After inserting a staple 22 and positioning the two tire casings as seen in Fig. 1 of the drawings, the lever 4 is operated, thus depressing the plunger 6 against the outer casing and then moving the two casings, the plate 17 and the guides 13 downwardly as a unit. This downward movement causes the rib 12 to drive the staple 22 through the casings, the ends of said staple being clenched by the anvil 7 as shown in Fig. 6. In order that all the staples may be placed the same distance from the edges of the easings, a gage 23 is preferably provided to abut the casing bead as shown in Fig. 1. said gage having a slot 24 through which set screws 25- pass for adjustably securing it to the standard 1..

From theforegoing, taken in connection with the accompanying drawings, it will be' seen that although my invention is of comarativel sim le and inex'ensive nature it will be highly efficient and reliable for stapling two old casings together, thus insuring additional mileage which could nototherwise be obtained thereby. By eement ing suitable fabric tape on the inside of the tire, over the heads of the staples, there is no danger whatever of the. latter injuring the inner tube and in actualuse, old casings stapled together by the machine have proven highly satisfactory, giving anywhere from one thousand to three thousand miles of service. The beads of theou-ter casing are preferably removed before stapling the two casings together, since this presents aneater appearance and does not impair the efliciency and durability of the reconstructed casing.

Since probably the best results are obtained from the construction shown and described, it maybe followed, but within the scope of the invention as claimed, numerous wn or changes may well be made.

. ment of said guide and spreader, and an anvil movable against the outer easing to shift the guide and cause said staple driver to copies of this patent may be obtained for project the staple through both casings, and

"clench it against the anvil.

"arm extending forwardly from said standard and having a vertical rib on its free end,

a vertically elongated staple guide slidably mounted around said rib, a horizontal work supporting plat'e'on the upper end of said guide, the front end of said plate inclining downwardly and forwardly and then downwardly and rearwardly to the lower end of said staple guide to form a wedge-shaped spreader for the casings, means for normally raising said guid and plate above said arm and for permitting downward yielding thereof to drive the staple, a plunger above said staple guide, a bearing carried by said standard and slidably receiving said plunger, and means mounted on said standard for depressing said plunger.

3. In a machine for stapling one tire casing upon another, a spreader for reception in the inner casing to hold it in contact with the other casing, means for normally retaining'said spreaderin a raised position and for permitting downward yielding thereof, a depressible anvil above said spreader for forcing the two casings and said spreader bodily downward, and means for forcing the staple through the casing when such movement takes place.

In testimony whereof I have hereunto set my hand.
